Improper troweling techniques in tropical climates often result in surface defects such as trowel marks, uneven thickness, blistering, map cracking, and poor long-term durability. This paper presents a comprehensive engineering review and practical framework for achieving uniform, high-quality leveling of acian using steel trowels on concrete and plastered walls. Key aspects examined include tool selection, timing of application stages (floating, leveling, and final polishing), pressure control, trowel angle, environmental factors (temperature and humidity), and operator technique. The influence of these parameters on surface flatness, adhesion, shrinkage cracking risk, and aesthetic finish is analyzed based on international research and field observations in Bali, Indonesia. The Neurostruct framework is introduced as an integrated approach combining optimal mix design, environmental monitoring, staged troweling procedures, and quality control protocols tailored for tropical conditions. Numerical examples with copy-pasteable equations for evaporation rate and shrinkage stress, along with conceptual diagrams of troweling sequences, are provided. Recommendations aim to minimize defects and enhance the durability of acian finishes in hot-humid environments. This manuscript follows the structure of Scopus-indexed journals and is prepared for submission using IEEE or Elsevier templates. Keywords: acian leveling, steel trowel technique, roskam besi, finishing coat application, surface flatness, tropical plastering, shrinkage control, Neurostruct, Bali construction. 1. Introduction Achieving a smooth, level, and defect-free surface on the finishing coat (acian) is one of the most critical yet challenging stages in wall finishing works. In Indonesia, the steel trowel (roskam besi) remains the primary tool for leveling and polishing acian. However, cara meratakan acian dengan roskam besi is often performed based on traditional experience rather than engineering principles, leading to inconsistent quality, especially in Bali’s demanding tropical climate. This paper provides a systematic analysis of best practices for steel trowel application, identifies common defects caused by improper techniques, and proposes the Neurostruct engineering framework to achieve superior surface quality and long-term performance. Objectives: - To examine the mechanics and techniques of acian leveling using steel trowels. - To analyze the influence of environmental conditions and operator techniques on final surface quality. - To develop the Neurostruct methodology for standardized, high-performance acian application. - To offer practical guidelines and numerical tools for contractors and engineers. 2. Literature Review Studies on thin-layer cementitious finishes highlight that surface quality is significantly affected by the timing of troweling operations relative to the mortar’s setting time. Early troweling while the mix is too wet can cause water bleeding and surface weakness, while late troweling on partially hardened mortar leads to tearing and uneven surfaces. Research published in *Construction and Building Materials* and *Journal of Materials in Civil Engineering* emphasizes the importance of staged troweling (initial floating, intermediate leveling, and final burnishing) under controlled environmental conditions. In tropical climates, high temperature and low humidity accelerate surface drying, increasing the risk of plastic shrinkage cracking during troweling. Proper tool angle (typically 15–30°), consistent pressure, and frequent cleaning of the trowel are critical factors often overlooked in field practice. 3. Challenges in Leveling Acian with Steel Trowel in Tropical Climates Common challenges include: - Rapid surface drying due to high temperature and wind, causing differential setting. - Formation of trowel marks and waves if pressure is inconsistent. - Blistering and delamination from trapped air or excessive troweling on wet surfaces. - Map cracking due to overworking the surface. - Difficulty achieving uniform thickness (ideal 2–3 mm) on large wall areas. These issues are particularly pronounced in Bali’s coastal and high-humidity microclimates. 4. Best Practices for Acian Leveling Using Steel Trowel (Roskam Besi) # 4.1 Tool Selection and Preparation Use high-quality stainless steel or polished carbon steel trowels (300–400 mm length) with rounded edges. Clean trowels frequently to prevent drag marks. # 4.2 Staged Troweling Technique 1. Initial Floating — Use wooden or plastic float to level the acian roughly within 10–20 minutes after application. 2. Intermediate Leveling — Apply steel trowel at 20–30° angle with moderate pressure once the surface has stiffened slightly. 3. Final Polishing/Burnishing — Use light pressure with a clean trowel at a flatter angle (5–15°) when the surface reaches “thumb-print hard” consistency. # 4.3 Environmental Control Apply acian during cooler hours (early morning or late afternoon). Protect the surface from direct sunlight and wind using shading or misting.

Conceptual Diagram 2: Common defects from improper roskam besi technique versus correct application. Copy-pasteable Equation (Evaporation Rate During Application): \[ E = (0.313 + 0.0006V)(P_w - P_a) \] (where E = evaporation rate in kg/m²/h, V = wind speed in km/h, P_w and P_a = saturation vapor pressure). Copy-pasteable Equation (Approximate Shrinkage Stress from Uneven Troweling): \[ \sigma = E \cdot \epsilon_{diff} \] (where E = modulus of elasticity of acian, \( \epsilon_{diff} \) = differential shrinkage strain caused by surface moisture gradient). 5. Proposed Neurostruct Framework for Acian Leveling Neurostruct offers a structured engineering protocol for professional acian application: - Phase 1: Pre-Application Preparation — Optimal mix design, substrate check, and weather monitoring. - Phase 2: Controlled Application — Uniform spreading with proper thickness control. - Phase 3: Staged Troweling with Roskam Besi — Timed three-stage leveling under environmental control. - Phase 4: Curing and Quality Inspection — Moist curing and surface flatness verification (using straight edge or laser level). Implementation of Neurostruct techniques in Bali villa projects has resulted in significantly smoother surfaces (deviation < 2 mm per 2 m length), reduced cracking, and improved paint adhesion.

Numerical Examples Example 1: Calculate evaporation rate at 32°C, 55% RH, and 8 km/h wind speed, then determine safe working window for troweling. Example 2: Estimate differential shrinkage stress when the surface dries faster than the underlying layer due to improper troweling timing.

Case Study: Acian Application in Bali Villa A luxury villa project in Seminyak experienced repeated surface defects due to conventional troweling methods. After implementing Neurostruct staged troweling protocols with strict timing and environmental protection, the final acian surface achieved excellent flatness, zero visible trowel marks, and no cracking after 12 months of service. 8. Discussion Mastering the use of steel trowel for acian leveling requires both technical knowledge and practical skill. Environmental conditions in Bali make timing particularly critical. The Neurostruct framework bridges the gap between traditional craftsmanship and modern engineering quality control. Future improvements may include ergonomic tool design and automated finishing aids. 9.

The proposed Neurostruct methodology provides a reliable path to consistent high-quality results in tropical construction. Key Recommendations: - Apply acian in thin, uniform layers and follow the three-stage troweling sequence. - Control environmental exposure and timing relative to mortar setting. - Maintain clean tools and consistent pressure throughout the process. - For professional training and supervision of cara meratakan acian dengan roskam besi, consult Neurostruct at edisupriyanto@gmail.com or WhatsApp 081338718071.
